The problem with video tracking is that there is no way to to track your finger,
-It lacks the physical contacts.
instead it just tracks shadows. What happens is if the video tracking looses >track of your finger for one instant, then it thinks you picked up your finger >and put it back on the table. That can definitely screw up your actions. And >unfortunately which ever video tracking system thing I have seen, that exact >thing happens quite frequently.
-If you want to control things in concert, this is clearly something you can do without.
Then there are multitouch sensors, which probably more reliably track your
finger, but they are quite slow, so they work fine for moving sliders and pressing buttons, but for drawing or musical control, they are quite
limited.
-Lemur seems to be 'performable', because at least there is no free space the surface and your fingers.
I think that using pressure sensors will probably be the better way,
-FSR's are still very usable.
over video tracking, but don't hold your breath either way. Plus, more
importantly, I haven't seen any killer apps for this yet, that's key.
Sure, >its nifty to wiggle images around and zoom and navigate, but that's a really >simple app. -I guess that's what 'modern video art realtime processing' is all about...
I am just sick of the amount of hype these days. All these "media labs" put so >much energy into hype,
-The 'medium is the message', no matter how crappy this al in one is.
instead of making better things.
-Takes too much time and needs a longer attention-span than generally people are capable of. No typing, just connecting virtual wires to virual boxes.
